Value Collection -12150-4 Black Union 3/4 Inch Npt Class 3000

Product Description

The VALUE COLLECTION -12150-4 is a 3/4-inch black union fitting designed for high-pressure piping systems in industrial and commercial applications. Manufactured from forged carbon steel with a black finish, this union provides a removable, pressure-rated connection point between two sections of threaded pipe. The Class 3000 rating and matching 3000 psi pressure rating make it suitable for demanding liquid and gas service where joint integrity is critical. This fitting is installed by licensed plumbers, pipefitters, and mechanical contractors working on high-pressure piping runs. Each package contains 2 unions.

This union fitting is used in industrial pipe assemblies, mechanical rooms, and process piping where a serviceable threaded connection is required. The NPT end connections make it compatible with standard tapered pipe thread systems. It is suited for both liquid and gas service lines operating at or below the rated pressure. The black carbon steel construction holds up in environments where corrosion-resistant coatings are not required and where robust mechanical strength is the primary concern.

Key Features

• Forged carbon steel construction for high mechanical strength in pressure service
• Class 3000 rating with 3000 psi liquid and gas pressure rating
• 3/4-inch NPT end connections for compatibility with standard tapered pipe thread fittings
• Black finish for use in systems where decorative or corrosion-resistant coatings are not specified
• Union design allows pipe sections to be disconnected and reconnected without cutting or rotating pipe
• Sold as a package of 2 units

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3/4-inch NPT threaded piping systems rated for Class 3000 service in liquid and gas applications.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable mechanical and plumbing codes, including IFGC and IPC requirements where gas or liquid service is involved. Shut off and bleed down all system pressure before disassembling or installing any union fitting. Apply an appropriate thread sealant rated for the service medium to NPT threads before assembly. Do not over-tighten the union nut, as this can damage the seating surfaces and compromise the pressure seal.
